Georgia towns of 2,500+ (264)Ahead of 41%
Few Georgia towns conserve much land (a typical one, 2%; the U.S., 4%), so Mableton’s 2% is ahead of 52% of Georgia towns, while its trails per square mile lead 58% of them.
How sure. Graded on any three of the four inputs instead, the letter would range from C to C+. Trails and many small parks come from OpenStreetMap, mapped by volunteers, so coverage varies from town to town; the half mile is a straight line from each census block, so a river or highway in the way isn’t counted against it.
